Hollywood is the fourth single from Jay-Z's latest solo album Kingdom Come. The song features Jay-Z's longtime girlfriend, R&B singer Beyoncé. The song is also featured on Beyoncé's B'Day Deluxe Edition with more of Beyoncé's vocals and less of Jay-Z's under the title "Welcome To Hollywood".

A video for Jay-Z's album version does not exist but an official video was created for "Welcome to Hollywood" using clips of different Beyoncé videos (much like the "Lose My Breath" megamix on the Destiny's Child Fan Pack II). The video is played as an interlude on Beyoncé's B'Day Tour, The Beyoncé Experience.
